The truth is, hardly any of us have ethical energy enough for more than one really inflexible point of honor.
No man who is occupied in doing a very difficult thing, and doing it very well, ever loses his self-respect.
Use your health, even to the point of wearing it out. That is what it is for. Spend all you have before you die; and do not outlive yourself.
Life does not cease to be funny when people die any more than it ceases to be serious when people laugh.
